Use of Diagnostic Ultrasound for Assessing Muscle Size

The Journal of Strength and Conditioning Research, 2002
The typical "gold standard" for assessing muscle size has been magnetic resonance imaging (MRI) and computerized tomography; however, these processes are very expensive and generally require a medical facility. The advent of B-mode diagnostic ultrasound (US) can perhaps offer a quick, cost-effective method to measure muscle size.

Identification of Genomic Predictors of Muscle Fiber Size

Cells
The greater muscle fiber cross-sectional area (CSA) is associated with greater skeletal muscle mass and strength, whereas muscle fiber atrophy is considered a major feature of sarcopenia.

Resistance Training Recommendations to Maximize Muscle Hypertrophy in an Athletic Population: Position Stand of the IUSCA

International Journal of Strength and Conditioning, 2021
Hypertrophy can be operationally defined as an increase in the axial cross-sectional area of a muscle fiber or whole muscle, and is due to increases in the size of pre-existing muscle fibers. Hypertrophy is a desired outcome in many sports.

Accelerated loss of trunk muscle density and size at L1 vertebral level in male patients with COPD

Frontiers in Endocrinology, 2022
Background and purposeWeight loss and muscle mass loss are common in patients with chronic obstructive pulmonary disease (COPD). Muscle density and fat infiltration based on CT images may be more sensitive than muscle mass by DXA in the assessment of ...

Short-term strength adaptation in isometric training to volitional failure depends on initial specific tension in elbow flexors

Journal of Physical Fitness and Sports Medicine, 2023
We tested a hypothesis that individuals with low maximal voluntary isometric contraction relative to muscle cross-sectional area (MVC/mCSA) would have greater strength gain compared to those with high MVC/mCSA in an early stage from beginning of ...

Cellular and molecular pathways controlling muscle size in response to exercise

The FEBS Journal, 2021
From the discovery of ATP and motor proteins to synaptic neurotransmitters and growth factor control of cell differentiation, skeletal muscle has provided an extreme model system in which to understand aspects of tissue function. Muscle is one of the few

An investigation of the relationship between lower limb muscle size, strength, and tibia length: A specific analysis of the hamstring and quadriceps muscles

ROL Spor Bilimleri Dergisi, 2023
The primary aim of this investigation was to assess the interrelations among the ratios of hamstring-to-quadriceps muscle size and strength, as well as the associations with hamstring and quadriceps muscle size, tibia length, and muscle strength.
